如何停止和销毁主线程（从中创建线程）

Question

I need to create, run, stop thread and then again same process (reloading some new data and need to refresh and cannot use C++11 standard). I have created and run thread like from mine main thread

pthread_t p;
pthread_create(&p, NULL, calculation, some_pointer_to_object);

How to stop and destroy this thread from main thread ? (pthread_exit is from current thread).

Answer 1

您需要使用pthread_cancel() 。

Answer 2

The only clean way to do so is this: Set up a flag in the main thread, start the thread, poll the flag in your new thread and finish fast if it's set. Everything else but letting your new thread close itself down cleanly on request opens a boatload of cans of worms, and that's an understatement.
